Serial No. 'eja To JZ whom it may concern: y Be it known that l, WERNER Orro, engineer, a subject o' the Grand Duke of Mecslenbiirg, residing at Berlin, Germany7 have i invented certain new and useful improvethe art to which it appertainsto 'make and 1 use the sainev Y' This invention relates to single .orinultiple inclosed high-tension electric oscillators of the typevin which. the space loetween reignboring'` electrodes is unoccupied 'by solid insulating medium.v

Oscillators according to the present 'invention comprise a easing containin electrode plates having substantially para lel opposing surfaces and insulating ineens arranged directly between said casing and said plates,

'suitable means beingemployed to maintain the plates at a suitable distance apa-rt.:

The invention also comprises the particular combinations hereinafter Adescribed and claimed. l in the accompanying drawing several constructional forms of the present invention are exemplified.

Figure l is a vvertical section through an arrangement, in WhichA all electrodes are made ol'thesaine type, each being arranged in a' cylindrical ring of a corresponding axial dimension. Fig. 2 is aplan view ot' F 1g. l, showing only one half of saine. Fig.

3 is an oscillator in which the terminal elec-I trodes are connected to sections of a casing' which consist each, oi a cylindrical portion and a flat end portion. Figs ato 6 show further constructions-1 forms both. in the general arrangement and the details.

With the oscillator according' to lFigs. 1

and 2 each electrode plate a is secured in av i ring c, an. insulating ring l), made for in stance of porcelain, being placed between then/i. The ring c is made, the same as the electrode plate, 4oif preferably 'a good heatgtogether. The insulating ring Zi is joined lto the ring e and the plate a by aid of a Esuitable inediuin, ior instance a cement.

When severalelectrodes are combined .in ,an oscillator, packing and. distancelrings al which apre preferably of instal are lplaced .between the rings c attached to the indi-l -vidnal electrode plates. Thel thickness oi "these rings rZ Will then determine .the dis-.-

ftance between the individual electrodes a, as the axial dimensions of the rings c and the plates c are equal, as has been hereinbefore said.

For the several elements consisting each f' of a plate a,. an insulatingv ring l; andan outer ring c to adjust themselves absolutely co-axially, centering rings e mayyas shown in Figs. l and 2 be slipped over the'y shell formed by the several rines c, so that each ring e will overlap the adverse ends of tvvo neighboring rings c.

The end electrode plates are furthermore i fitted with pole binding posts u by ineans of which the oscillator is connected to an electric circuit. ln. the drawing it has been assumed, that thewhole oscillator consists of the two end elements the electrode plates of which are fitted .with pole binding posts u and a single intermediate element. course any number of intermediate elements may be employed and the oscillator may also be inade of only two elements yvvith pole binding posts without any-intermediate ele-4 4ments, so that a single oscillator isobtained. y* According to ll`i'gs. l and 2 means are further provided for rigidly connecting the in; dividual oscillator eleuments With each other in an axial direction. For this purpose the rings c holding the end-electrodes have outwardly projecting lugs f, g. Through bores in these lugs are passed bolts h, having a head lil at one end, and a thread h2 at the other. By means of nuts e' the screw-bolts h can be tightened and thereby the several eleinents may be axially pressed together. .ln sonic cases the above described tightening arrangement is dispensable, as it may be' sucieiit to loosely superpose the several elements.

conductor, copper.` rl`hc axial dirnen-' sion of the ring o corresponds to the thick- 50 nessof the elect-rode plate a; An accurate With the larrangernent according to Fig. 105

requality of these dimensions may be easily 3 the several elements of the oscillator 'are obtained, by rigidly combining the elcc- Centered with regard to each other by means trode plate with the insulating ring and the ofcentering" rings e arranged on the inside W ring c, and then grinding down or other- Iof the rings c. Here the end-electrodes are if Wise machining the plate a and the'ring. o not secured to lrings oit the same axial diil@ "fdrical portion and a ilat end portipn.

Icourse theend-electrodes, from which conmension, lilrei the central electrodes., but'to a section of the casing composed ofpau cylinnection bolts al lead .axially outward for allowing of connecting, the feeder cables, are

vinsulated from their casing-sections. by

*structional formit is'possible to iobtain a single oscillator by omitting the intermediate electrodes, in which; case. the casingsections of the two end/electrodes 'alone will form the casing.

With the constrctional form according to Fig. 4 ringsZ are arranged between the rings eeseriging at theA same time as guide and distance rings. The rings Z are of aconsiderably greater axial dimension than the distance of the electrodes required. The

rings 0 are correspondingly recessedand the ing surfaces, a casin corresponding to the single electrode plates,

rings Z fit into these recesses. This 'arrangement has the-advantage, that in consequence ofthe greater axial dimension of the rings Z the working of them is facilitated. f Ingthe construction of an oscillator element shown in Fig. 5 the electrode plate a, has at its edge a projecting' web p which enga es ina groove g 1n the split ring b.

ith the arrangement accordilw to Fig. 6 each electrode a is provided wit an annular groove m in its circumference, which groove is engaged by an inwardly projecting web r of the metallic ring c'. The electrode Aconsists of two plates, between which a distance-disk 'a has been arran ed, and which are held together by means o a rivet o. Be-

tween the web r and the 'electrode is ar ranged a layer of insulating material. s,

which extends up to the ring jc. As insulating "material for this purpose mica or any other suitable material may be employed.
